PowerApps dropdown not updating SharePoint list

So I am having issues with dropdowns that are referring to secondary list to obtain their input options.

All of these dropdowns are using a formula similar as the following for the Item function:Sort(Distinct('SecondaryList ', Column ), Result)

**These dropdowns are in a form/DataCard which is sending the info to the main SharePoint list**

I did correct the Update function to refer to the new dropdown box but I am still getting no information in my main SharePoint list when the form is submitted... any idea what the problem might be and how to solve it?

Other dropdowns which have Item function define as the choices for my main SharePoint list are sending info to the main SharePoint list without any problem.

Also the column in my main list are set up as choice columns and the ones in my secondary lists are set up as single line of text input. I tried changing them to choice columns but i dont get my options for my dropdowns...
